jyknight added a comment.
I wonder if we actually need to define a clang frontend flag for this; I
suspect nobody will ever want to specify it, since the only non-canonical
personality clang will ever generate that changes behavior is the pure-C
destructor-only personality, `__gnu_personality_v0`. Otherwise, it could only
arise from assembly or IR.
For a test-case, can just use `-mllvm -emit-compact-unwind-non-canonical`.
================
Comment at: llvm/lib/MC/MCAsmBackend.cpp:119
+
+bool MCAsmBackend::isDarwinCanonicalPersonality(const MCSymbol *Sym) const {
+ if (Sym && Sym->isMachO()) {
----------------
This could use a comment as to why these two are "canonical" and why
"__gcc_personality_v0" is excluded despite being similar.
